This is truly nightmare material. I shudder to think how this could be used to extract information from someone once the tech progresses to where it's possible to communicate with these brains.

I think we’d soon find out that a brain without a body operates very differently than when the brain is in the body. The brain relies on the body’s sensory organs for much of its decisions, how can it compute things when these are removed?

And also - if we managed to extract data from a brain, could we hold someone guilty for what we pull out? Would the brain say different things than the mouth? Which one is correct?

I don't really see what impact this has on our ability to extract information from a person's brain. We can already stick brain-computer interfaces into a brain while it's attached to the rest of a body. The significance of this technology combined with BCIs is in my opinion positive; that people may be able to have a meaningful conscious existence without a body, beyond their natural death.
